How to get Your Schedules displayed on
Online Maps using the General Transit Feed
Specification (GTFS)

This white paper discusses the key considerations for transit companies that want their
organisations routes and schedules to appear within online mapping services such as Google
Maps. Key steps in publishing the organisations data in the General Transit Feed
Specification (GTFS) and the associated people and process impacts are discussed. The key
takeaway is GTFS is now a viable solution for transit companies that are seeking to provide
great customer service while at the same time helping to minimise their ongoing technology
costs.
A key challenge for providers of public
transportation is making their routes and
schedules easily accessible to the travelling public.
Historically, this involved paper based schedules
supplied to both the passengers and displayed at
key stops, later being supplemented with call
centre customer service and more recently
company specific websites. With the advent of
smart/internet enabled mobile phones, passengers
are now expecting mobile accessible, always
available 24x7 schedules that have current
information and regularly improving user
interfaces. The cost to develop & maintain
customised company specific mobile apps can be
over $300K USD. Alternatively, you can choose to
adopt the General Transit Feed Specification
(GTFS) and utilise mobile apps, widgets, webpages
and other related software that companies such as
Google, Bing, Here and TransitApp are already
making freely available to your passengers.
into the GTFS format. The level of detail that will
be captured and presented in the initial GTFS file
release can range, with often the most basic
necessary information with made available in the
first release. Stop information can detail the
amenities available such as car-parking, seating,
shelters and wheelchair accessibility. Basic fare
information can also be included. However, often
the largest challenge in the first release of a GTFS
file is obtaining consistent and correct information
for the entire network. Reviewing, cleansing and
fixing inconsistencies are key to providing
passengers with quality online schedules. Due the
transit agencies personnel inexperience with the
GTFS format and the desire to keep these team
members focussed on day to day operations, often
a company that specialises in GTFS files, such as
AddTransit, is used to assist in the creation of the
files.
Routes, Schedules & Stops
The General Transit Feed Specification (GTFS) is a
internationally accepted format for public
transportation
schedules
and
associated
geographic information. A GTFS file is a group of
zipped (compressed) CSV files, which together
contain enough information to support route and
journey planning software.
Although the
individual CSV files are relatively simple in format,
the challenge is that smaller transit operators
don’t have the necessary IT background and spare
resources to create and maintain such files.
The GTFS file is considered a static file; that is the
information does not change moment by moment.
However in transportation even a static schedule
has many variations. Routes adjust for seasons,
school hours or peak times. Special event services
are scheduled months in advance for sports, shows
or festivals. Some stops may be used as time point
for certain services and be express for others.
When the GTFS file is created all these known
variations need to be understood and
incorporated.

No one knows your network like your people, but
they are also probably so close they will
sometimes miss things that are inexplicable to
outsiders. Some examples that we’ve seen include
such things as stops with the address being a store
name that has long since moved locations,
changes to street names that have not been
reflected in internal company systems and route
maps that are adequate but could not be used for
navigation. Completing an initial review or GTFS
Needs Assessment of a sample route is the first
step in determining how complete the company
data is and how much will need to be fixed or
gathered from scratch either manually or using
automated tools such as GPS mobile apps.
To ensure a timely outcome, a contact person
within the company must be selected and given
the authority to obtain clarifications from across
the business. It is highly likely that previously
unknown gaps in routes and schedules will be
uncovered and this may give the opportunity for
some quick organisational wins, while the GTFS file
is being created. However, it is important that the
clarifications are prioritised and if they are not
necessary for the first release, consider providing
that data in a later release.
After the testing performed by GTFS service
providers and the software platforms, you will
want one of your staff to test the output from the
GTFS file to prove that it is working successfully. It
is important that this person is identified early, so
that they can be prepared to test when the time
comes. This testing is a key signoff step prior to
the file being made available for public use.
Preparing for Release
The GTFS file can be used by multiple companies
to display data, including Google, Bing, Here,
Transit App, accessible software providers and
many more. Another use for GTFS data is to
include it on real estate services such as
WalkScore. It is up to you whether you make your
GTFS file available to everyone or just specific
companies. It should be noted that the general
[email protected]
public now expects transit information to be
available on whatever their preferred platform and
software is and limiting the release of GTFS file
could result in negative consumer feedback. As
each software company that uses GTFS files have a
different submission process, using a company
such as AddTransit that is familiar with the various
submission processes can make the submission
process easier.
Consideration should also be given to brand and
licencing arrangements for the GTFS file. In
essence you are providing your existing data in just
a new format, however to ensure brand
consistency you may want to specify licencing,
liability and preferred logos/colors that can or
can’t be used. We advise you discuss these
implications with your branding, marketing and
legal representatives to ensure that you fully
understand any implications for your business.
You will also need to determine how you will make
the public aware of this new service. Will you
announce it going live as each particular software
platform brings your file to life? Will you only
announce one particular software platform (e.g.
Google, Bing, Yahoo/Here)? Or maybe you will opt
for a soft launch and let customers find out for
themselves. Each option has its merits and this
will be a company specific decision.
Preparing for Modifications/Maintenance
Routes and schedules will change, so it is
important that prior to releasing the GTFS file that
your ongoing maintenance process is established.
If the file becomes out of date, it will damage your
brand and may be removed from the maps and
apps. Therefore, a role within your company must
be assigned the responsibility for keeping the GTFS
file up to date. A periodic refresh of the file should
be agreed, along with a process for ad-hoc
updates. Building a robust internal process will
allow you to ensure changes are made available
ahead of time.

Going live – Your first Release
It is vital that the first release of the GTFS file is
monitored as it goes live. Having your GTFS
service provider perform spot checks along with a
more formal first release test plan will give you the
confidence that your well tested GTFS file has now
successfully transformed into a new customer
service offering.

Determining the right balance for what additional
data will be added to the GTFS file will depend on
customer needs and company capacity. E.g. If you
can’t maintain the information in the GTFS file
about the number of seats at a particular stop,
then you probably should not include it.
Additionally you may decide to further supplement
the GTFS route and schedule information with
Real-time updates and vehicle positions. You can
also choose to use the GTFS file as the basis for
What next step you will take in your GTFS journey?
Ongoing and next steps
As mentioned earlier, it is essential that the
maintenance steps are followed and as each new
release is performed the data is kept current.
Online Ticketing, sales and booking management.
However each step should be considered on its
own merits and taken only when your organisation
is ready to move to the next level.
